I tell when asked. Mostly because I am selfish. I love to see the shocked look on their faces when I tell them I have lost 48 lbs so far and have 64 more lbs to go. I also like seeing the shock when I tell them what size I wore and what size I am in now. I am evil.. hahahaha
They tell me that I will be too skinny if I lose an additional 64 lbs more, but then I tell them I started out at 262 lbs and want to end up at 150 lbs. They looked shocked again, and tell me that I didn't look, nor do I look, like I weigh that much. One person commented that I carried my weight well... carried my weight well???? One even said I didn't walk like I was a fat person.
So, how does a fat person walk? Dunno.
This doesn't embarrass me, in fact - it actually keeps me on track for myself.
